I want to take 10000 examples of keil. I can't get char samples [10000] either. Do you have a solution?
My code is below.
#include <stm32f4xx.h>#include <stm32f4xx_rcc.h>#include <stm32f4xx_adc.h>#include <stm32f4xx_gpio.h>
ADC_InitTypeDef ADC_init_structure; //Structure for adc confgurationGPIO_InitTypeDef alper; //Structure for analog input pin float dum1;int ms10Ticks; /* counts 1ms timeTicks */
/*---------------------------------------------------------------------------- SysTick_Handler *----------------------------------------------------------------------------*/void SysTick_Handler(void) { ms10Ticks++; ADC_SoftwareStartConv(ADC1);//ADC1->CR2 |= (1<<30);}
/*---------------------------------------------------------------------------- MAIN function *----------------------------------------------------------------------------*/int main (void) { char huge samples[10000]; int i=0; RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOD,ENABLE); RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOC,ENABLE); RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1,ENABLE); GPIO_StructInit(&alper); alper.GPIO_Pin = GPIO_Pin_5;//The channel 15 is connected to PC5 alper.GPIO_Mode = GPIO_Mode_AN; //The PC5 pin is configured in analog mode alper.GPIO_PuPd = GPIO_PuPd_NOPULL; //We don't need any pull up or pull down GPIO_Init(GPIOC,&alper);//Affecting the port with the initialization structure configuration
//GPIOC->MODER |= (3<<10); // PC5--> ADC.15 input olarak ayarla //GPIOC->PUPDR = 0x00000000; // pull up-down yok
ADC_DeInit(); ADC_init_structure.ADC_DataAlign = ADC_DataAlign_Right;//data converted will be shifted to right ADC_init_structure.ADC_Resolution = ADC_Resolution_12b;//Input voltage is converted into a 12bit number giving a maximum value of 4096 ADC_init_structure.ADC_ContinuousConvMode = DISABLE; //the conversion is continuous, the input data is converted once ADC_init_structure.ADC_ExternalTrigConvEdge = ADC_ExternalTrigConvEdge_None;//no trigger for conversion ADC_init_structure.ADC_NbrOfConversion = 1; ADC_init_structure.ADC_ScanConvMode = DISABLE;//The scan is configured in one channel ADC_Init(ADC1,&ADC_init_structure);//Initialize ADC with the previous configuration //Enable ADC conversion ADC_Cmd(ADC1,ENABLE); //Select the channel to be read from ADC_RegularChannelConfig(ADC1,ADC_Channel_15,1,ADC_SampleTime_144Cycles);
SystemCoreClockUpdate(); /* Get Core Clock Frequency */ if (SysTick_Config(SystemCoreClock / 10000)) { /* SysTick 10 msec interrupts */ while (1); /* Capture error */ }
while(1) { /* Loop forever */ if(ADC_GetFlagStatus(ADC1, ADC_FLAG_EOC)){//if((ADC1->SR & 0x00000002)){
dum1=(ADC_GetConversionValue(ADC1)); samples[i]=dum1;// BURAYA KODUNU YAZ….örnegi burda aliyor…dum1 içerisine. i++; if(i==10000) i=0; } }
}

How could we? You haven't described any problem to the level of detail that would allow even discussing possible solutions sensibly, much less just handing you a solution gift-wrapped and ready to use.
